CONTROLLING-ENGINE FOR PR'EssEs,

SPECIFICATION forming part of Letters Patent No. 637,569, dated November 21, 18 99. pp at n fi September 3, 1898. Serial No. 690,480. (No model.)

To in whom, it may concern.-

I Be it known that I, EDWARD HETT, of New York, (New Dorp,) in thecounty of Richmond, State of New York, have invented certain new and useful Improvements in Controlling-Eugines for Presses, of which the following is a specification. I

My invention relates to presses, and more especially to devices for controlling the movements of parts of theme chanism of presses as,for example,for controlling the movements, in a lithographic press, of the printing-surfaces, the inking mechanisms, and the damping mechanisms into and out of operative position. I

It has for its object to provide means for controlling the movement of parts of presses, especially movements'of parts of the press into and out of operative position, to effect such control more easily, readily, efficiently, and with greater precision and certainty than has heretofore been possible, and to provide means for this purpose which are simple in character, eflicient in operation, and which enable the operator at all times to maintain control over the movements of different parts of the press.

It has also for its object to provide means automatically operated by the part of the press to be moved at the limit of its movement for automatically stopping the movement of such part at a predetermined point in order to insure against breakage and to attain greater precision and certainty in the move-- ment of such part. j

My improved devices are primarily intended to be used with and are here'described as appurtenant to a multicolor lithographic printing press such as is shown and described in my application for a patent filed Junel, 1898, known as Serial No. 593,796; but I do not limit my improved devices here shown and claimed to use in such a press, as it is evident that they can be employed with advantage in any lithographic or other press in which rollers'for printing, inking, damping, or other similar purpose or other parts of the press are to be movedas, for example, toward or away from an impression-drum or printing-surface.

, In the operation of the multicolor-press in connection with which my improved devices are here shown and described it is necessary to move the entire series of printing-surfaces out of or into contact with the impressionsurface, to move the inking mechanisms out of or into contact with the printing-surfaces by swinging the ink-frames carrying the inking, mechanisms, and to move the damping mechanisms out of or into contact with the printing-surfaces by swinging the dampingframes carrying the damping mechanisms, and it is in connection with these movements and to control them that my improved devices are herein shown and described.

In thepreferred form of my improved controlling-engine shown and described herein I employ connecting mechanism or mechanisms between the driving mechanism of the controlling-engine hereinafter referred to and the part or parts of the press to be moved connecting the said driving mechanism with the said part or parts of the press-driving mechanism, preferably driven by the driving mechanism of the press, for imparting motion through the said connecting mechanism or mechanisms to the said part or parts of the press to be moved, and suitable clutch mechanism, preferably electric, to connect and disconnect the driving mechanism of the controlling-engine with some suitable source of power, preferably the driving mechanism of the press, and to connect the said driving mechanism of the controlling-engine with the said connecting mechanism or mechanisms and to disconnect them. Iprefer to use in my controllingengine driving mechanism which is capable of motion in either direction, as I am thus enabled, by the use of the same controlling mechanism, to impart to the part or parts of the press to be moved a movement one way or the other, as desired. Such movement one way or the other I obtain by employing, preferably between the source of power and the driving mechanism of the controlling-engine, clutch mechanism preferably which is capable of assuming any of three separate positions, in one of which the source of power is wholly disconnected from the driving mechanism of the controlling-engine, in which case the part or parts of the press to be moved remain at rest, and in the other two of which positions the driving mechanism of the controlling-engine is connected with Q Be ated the source'of power, in one of said positions to impart motion in one direction to the 'dr iv other way. My preferred form of mechanism for this purpose is shown in the drawings and consists of two clutch gear-wheels, intermediate between the source of power and the main-shaft of my controlling-engine, and. a clutch adapted to cause one or the other or neither of the clutch gear-wheels to connect the source of power with the said shaft, although of course any other mechanism suitable for the purpose may be employed. 6

I will now proceed to describe the particular form ofcontrolling-engine shown in the drawings herein.

graphic press such as is shown in'my said application for a patent,'Serial No. 593,796,"

with the casing removed and with certain parts broken away to show more fully the op- I eration of the parts. 7 Fig. 2 is a diagrammatic plan showing the circuits preferably used by me in the operation of my controlling-engine. Fig. 3 is a sideviewof .a hand= wheel and connections and the standard upon which it is mounted for operating the circuitcontrollers hereinafter described. Fig. 4 is a vertical cross-section through the 'upperpart of the said standard, and Fig. 5 is a plan of the same. Fig. 6 is a side view of a part of the said multicolor-press, taken on the side of the press where the controlling-engine is located, but with the controlling-engine omitted and the casing removed. Fig. 7 isa similar view of the other side of the press. Figs.

Figs. 10 and 11 are similar details of means for automatically stopping the l in Figs. 1, 6, and 7 is located.

1 ;is the shaft upon which impression-drum -2 of the multicolor lithographic press show-n color lithographic press is substantially the same as that shown and described in my said application, SerialNo. 593,796, and the mechanism of it will not be .described'in detail any further than is necessary to convey a clear idea of the connection therewith of and the control of the operation of certain parts thereof by my improved controlling-engine. The parts of this press which are moved into or out of operative position by means of my controlling-engine are the printing-cylinders 3 3, damping-frames 4. 4, and the inkingframes 5 5. The mechanism by which my controlling-engine moves these into or out of operative position will be presently described.

My controlling-engine proper has 'a-shaft which is preferably adapted to rotate in either I direction and is preferably driven by the driving mechanism of the press and is connected by connecting mechanism, to be presv ently described, with the printing-cylinders, I Figure 1 is a side view of such controllingf engine and of a part of a multicolor lithodamping-frames, and inking-frames. This shaft is shown in Fig. 2'as a-single shaft6; but I-prefer in place of a single shaft to use two shafts for the same purpose" These Shafts are the shafts 6 6 as shown in- Fig. 1. This shaft is provided with gear-wheels and with clutchmechanism, preferably electric. It is. immaterial whether one or two shafts be used, as the effect is substantially the same in both cases. Iprefer' the double form (shown in Fig. 1) for the reason that the gear-wheels can be placed upon one part of the compound shaft and the electric clutch mechanism upon the other part, thus enabling a shorter shaft to be usedand the mechanism to be made more compact and smaller in size. The-shaft of the controlling-engineis prefer,- ably driven by the driving mechanism of the press, although anysuitable driving mech* anism may be employed for that purpose.

As shown in Fig. 1, the main driving-shaft '7 of the press carries at one end a beveledgearwheel 8, which meshes with gear-wheel 9. upon shaft 10. Shaft 10 carries at its other end a beveled gear-wheel 11. v

In order to impart motion to the shaft of the controlling-engine in either direction, as desired, two clutch gear-wheels'12 12 are interposed between the shaft and beveledgearwheel 11. Gear wheels 12 12 areloosely ,mounted on the shaft 6 (shown in Fig. 1)

and mesh with gear-wheel 11. As shown,each

sleeve 13, each of which sleeves turns loosely on the shaft 6 and also carries at its other end gear-wheel 14., the latter meshing with gear-whee11'5, loosely mounted upon shaft 6*.

1 16 and16 are the two parts of an electric clutch for connectingeach g eat-wheel 15 with.

shaft 6 part 16 of the clutch being connected with shaft 6 so as to be capable of mo tion longitudinally along the shaft, but rotating with the shaft. This may be accomplished by any well-known means-such, for

instance,as by spline and feather. -Part 16 is integral with gear-wheel 15 and is loose 7 x; 1

'gear-wheel12 is rigidly secured to a separate upon the shaft 6. The form of this clutch mechanism may be-ofanysuitable kind. Details are accordingly not shown. This electric clutch mechanism is so arranged that,

when the current is passed through it, the two parts of the clutch mechanism will lock together, thus causing shaft 6 to rotate in one direction or the other, depending upon which of the electric clutch mechanisms 16 16 is energized. In this way the shaft of the controlling-engine is driven one way or the other, as desired.

17 is a gear-wheel loosely mounted upon shaft 6.

18 and 18 are the two parts of an electric clutch mechanism for connecting the 'gearwheel 17 with shaft 6 the part 18 rotating with shaft 6 and movable longitudinally thereon, and part 18 being integral with gear-wheel17. Gear-wheel19, mounted upon sleeve 20 on shaft 6*, meshes with gear-wheel 17. Sleeve 20 also carries gear-wheel 21. Then electric clutch mechanism 18 18 is energized, gear-wheel 21 rotates one way or the other, depending on the direction of rotation of the shaft 6*. Gear-wheel 21 is intermediate between the shaft of the controlling-engine and the connecting mechanism connecting the controlling-engine with the inking-frames. This connecting mechanism is as follows, namely: beveled gear-wheel 22 on shaft 23, beveled gear 24 on the other end of the shaft meshing with beveled gear 25 on shaft 26, the latter carrying at its other end gear-wheel 27, gear-wheel 28 on shaft 29 meshing with gear 27, worm 30 on said shaft meshing with worm-wheel 31, mounted on shaft 1 of the press and having teeth 32 on its face, beveled gear 33 on shaft 34 meshing with teeth 32 and carrying at its other end the worm 35, which meshes with worm-wheel 36, secured to inking-frame 5. Each inkingframe has a similar worm-wheel 36, shaft 34, with worm 35, and beveled gear-wheel 33 meshing with the same teeth 32 on wormwheel 31. Thus Whenever clutch mechanism 18 18 is energized the shaft of the controlling'eng ine, through gear-Wheel 21 and the above described connecting mechanism, moves all of the inking-frames of the press simultaneously into or out of operative position, depending upon which one of the two electric clutch mechanisms 16 16 is energized. If one is energized, the inkingframes are moved so as to throw the inking-rollers into operative position,and if the other clutch mechanism 16 16 is energized the inkingframes are moved so as to move the inkingrollers out of operative position.

Shaft 26 carries two gear-wheels 25 and 27, one on each side of the outer frame of one side of the press, the inner one meshing with a beveled gear 28 ona shaft29, having a worm 30 meshing with a similar worm-wheel 31, having similar teeth 32. Each inking-frame on one side of the press is similarly provided with a worm-wheel 36, a worm 35 on shaft 34, and beveled gear. 33, meshing with teeth 32. The inking-frames at the other side of the press are connected by any suitable means to the'inking-frames thus driven by the worm 35. Accordingly when electric clutch mechanism 18 18 is energized all the inkingframes on each side of the press are simultaneously swung so as to move the inking-rollers into or out of operative position, depending upon which one of the two electric clutch mechanisms 16 16 is energized.

The mechanism for moving the damping frames so as to bring the damping-rollers into or out of operative position consists of the following:

37 is a gear-wheel loosely mounted upon shaft 6 38 and 38 are the two parts of an electric clutch mechanism for operatively connecting gear-wheel 37'to shaft 6, 38 revolving with shaft 6 and having longitudinal motion thereon, as by spline and feather, and 38 being fixedly secured by sleeve 39 to gear-wheel 37.

40 is a gear-wheel mounted upon sleeve 41, loosely mounted upon shaft 6", said sleeve also carrying beveled gear-wheel 42. When electric clutch mechanism 38 38 is energized, gear-wheel 42 is rotated one way or the other, depending upon the direction of rotation of shaft 6, in the manner above described. The connecting mechanism between gear-wheel 42 and the damping-frames of the press consists of the following-described mechanism: beveled gear-wheels 43 on shaft 44, the latter carrying at its other end beveled gear 45, beveled gear 46 upon shaft47 meshing with beveled gear 45, worm 48 upon shaft 47 meshing with worm wheel 49 upon shaft 50. Shaft 50 runs across to the other side of the press and through the frame and carries atits 57, fixedly mounted on 'shaft 56 and working in a similar-shaped opening in wheel58, loosely mounted on shaft 1; arms 59, each provided with fingers encircling a pin 60, secured to wheel 58, and each pivoted at 61 and having crank-arms 62 63, the latter connected to a damping-frame 4. On the nearer side of the machine there are also parts corresponding to beveled gear 51, shaft 53, with its gear 52 and worm 54, gear-wheel 55, shaft 56, eccentric 57, wheel 58, and arms 59 and the other connections, so that each set of damping-frames is slightly rocked one way or the other whenever electric clutch mechaning-frames has a corresponding arm 59, pin

IIO

60, and crank-arms 62 and 63, so that all of the dampingframes of the press are simultaneously rocked backward or forward, so as to move the damping-rollers into or out of v shaft 6. 65 and 65 form electric clutch mechanism for operatively connecting gear-wheel 64 with shaft 6, 65 rotating with said shaft and being capable of longitudinal motion thereon, as above described, and 65 being integral with gear-wheel 64.

66 is a gear-wheel loosely mounted upon shaft 6. As electric clutch mechanism 65 65 is energized, gear-wheel 66 is caused to rotate one-way or the other with shaft 6,.de-

pending upon which one of the two electric clutch mechanisms 16 16 is energized. The connecting mechanism between gearwheel 66 and the printing-cylinders consists of the following mechanism: gear-wheel 67 on shaft of the toggle-joint, toward the center of the press, being free to move radially inward or outward from the center, the outward end of the toggle-joint being secured to the framework at ,78. To the inner end 79 of each toggle-joint is secured a shaft 80, carrying at its outer end one of the bearing-boxes 81 of a printing-cylinder. toggle-joint arrangement carries the other bearing of the printing-cylinder at the other sideof the machine. There is a similar arrangement of toggle joint and shaft con nection between each bearing of each print-.

ing-cylinder of the press and each wheel 74 as that above described. Accordingly, as

' wheel 74 moves one way or the other when electric mechanism 65 is energized and one or the other of electric clutch mechanisms 16 16 is energized, the printing-cylinders are moved inward against the drum, or in operative position for printing, or are moved outward therefrom. By means of the two clutch gear-wheels 1'2 12 and their respective clutch mechanisms 16 16, intermediate between the shaft of the controlling-engine and the drivin'g mechanism of the press, I am enabled to rotate the shaft in one direction or the other,

as desired, by energizing one or the other of the said electric clutch mechanisms, and by means of each gear-wheel and its respective electricclutch mechanism, intermediate be- 65 tween the shaft of the controlling-engine and the connecting mechanism connecting with the different parts of the press to be moved,

A similar shaftwith its may be itself controlled by the operator in any suitable manner and by any suitable means. I prefer, however, to efiect such control by means of electric circuits which are controlled, preferably, by circuit-controllers under the control of the operator, as hereinafter described. I have shown in Fig. 2 and will now proceed to describe my preferred system of electric circuits for this purpose.

In my preferred system I employ a series of circuits, preferably normally open, one for each electric clutch mechanism, and these circuits, for purposes of clearness and conciseness, I will designate as clutch-circuits. When the clutch-circuit of any clutch mechanism is closed,the said clutch mechanism will be troller, and this energizes an electromagnet in said circuit, the latter attracting the cir- 'cuit-controller of its corresponding clutch-circuit, closing said circuit. As the closing of the operating-circuits by the operator is but momentary, I employa catch for seizing and holding the circuit-controller of the clutchcircuit in its closed or operative position, thus keeping the clutch-circuit, through the clutch mechanism, closed until it becomes necessary to open it. To release these catches and break the clutch-circuits, I have arranged a series of circuits, which I will refer to as releas ing-circuits, each containing an electromagnet adapted, when operated, to withdraw the catch, so as to release the said circuit-controller of the clutch-circuit to permit it to open and break the clutch-circuit. I preferably place a circuit-controller in each of the releasing circuits, which is adapted to be closed to make the releasing-circuitv and to energize an electromagnet therein to withdraw the catch for the above purpose, and I preferably arrange this so that the part of the press which is being moved will at the limit of its movement automatically close one of the said releasing-circuits, and thus break the circuit through the clutch mechanism which connects the said part of the press and its connecting mechanism with the shaft of the controlling-engine to insure the stoppage of the said part of the press at the proper time and to prevent breakage of the parts. This mechanism will presently be described.

In Fig. 2 I have shown a diagrammatic plan of the various circuits referred to above. In this figure I have shown the shaft 6 of the controlling-engine as being composed of but one part and as carrying the gear-wheels 12, 21, 42, and 66, here shown as spur gearwheels,.connecting with the various trains of gearing comprising the connecting mechanisms connecting with the different parts of the press to be moved, and also corresponding clutch mechanisms 16 16 18 18*, 38 38 and 65 65 as arranged upon the one shaft 6.. This construction, however, is in all substantial respects the same as that shown in Fig. 1, Where the shaft of the controlling-engine consists of two separate shafts 6 6 In Fig. 2 I have not represented the driving mechanism of the press, nor have I-shown the connecting mechanisms connecting the different gear-wheels with the different parts of'the press to be moved.

The clutch-circuits and operating-circuits referred to above are placed under the control of the operator by means of the handwheel and circuit-controllers shown in Figs. 3, 4, and 5, in which 82, 82, 82, 82, 82 82 82 82 82", and 82 are metallic studs mounted in a plate 83, made of wood or other suitable insulating material and connected at their lower ends by wires, as hereinafter described. Plate 83 has on its upper surface a metallic ring 85, connected by Wire 86 with a main-line wire 87, running through switch 88 to one pole of the battery or other source of electricityas, for instance, to the negative pole. Hand-wheel 89 is mounted upon a sleeve 90, adapted to turn loosely on stationary stud 91, which is secured to plate 83, as shown in Fig. 4. Sleeve 90 carries insulating material 91, and also secured to this insulating material is a ring 92, which has two projecting fingers 93 and 94, the former, 93, hearing down upon and making contact at all times with metallic ring 85, and finger 94 making contact with metallic studs 82 82 &c. as the hand-wheel is turned. 1 Whenever 94 rests upon the top of one of the studs 82 82", &c. ,it closes a circuit, as will hereinafter be de scribed. Ring 92, with its fingers 93 and 94, thus forms a circuit-controller which is under the control of the operator. As the operator turns hand-wheel 89 from one stud to the other he successively closes and breaks different circuits, as will be presently described.

In order to lock the handwheel in any given position and also to cause the fingers 93 and 94 to make better contact with ring 85 and the different metallic studs, I have placed a screw-thread 95 upon the upper part of stud 91 and have placed upon such portion of the stud an encircling plate 96, normally held out of contact with hand-wheel 89 by means of spring 97 and also handle 98, similarly interiorly screw-threaded. By turning handle 98 in the proper direction the plate 96 will be forced down upon hand-wheel 89, looking it and forcing fingers 93 and 94into better contact with ring 85 and studs 82 82", &c. The finger 94 stands normally in contact with stud 8%, as shown in full lines in Fig. 2. In this position the machine is at rest.

The different clutch mechanisms on the shaft of the controlling-engine are operated by a series of circuits, one for each clutch mechanism, which circuits for purposes of clearness and brevity I will refer to as clutch circuits. Each of these clutch-circuits has a circuit-controller adapted to make or break the circuit. Each of these circuit-controllers I place under the control of an electromagnet in another circuit. The latter series of circuits I will refer to herein as operating-circuits. Each of these operating-circuits is directly under the control of the operator by means of the hand-wheel 89 and the fingers 92 and 94 and studs 82 82 &c. In addition to these circuits I also provide what I term releasingcircuits. These circuits each contain an electromagnet which is adapted to withdraw a catch to permit the circuit-controller of each clutch-circuit to open or resume its inoperative position. placed under the direct control of the operator, and others are preferably placed so as to be automatically controlled by the movements of the different parts of the press as they reach the limit of their movement.

I will now proceed to describe the various circuits operating the clutch mechanism. In this description I will describe the circuits as they are successively operated by the operator as he turns hand-wheel 89.

Hand-wheel 89 rests normally so that finger 94 rests upon stud 82 In this position the machine is at rest. He then turns the handwheel so as to bring finger 94 upon stud 82 This closes the following operating-circuitnamely, from the negative side of the source of electricity through switch 88, wire 87, wire 86, ring 85, finger 93, ring 92, finger 94, stud 82, wire 99, electromagnet 100, wire 101, main-line wire 102, switch 88 to positive side of the source of electricity. This energizes magnet 100 and pulls forward circuit-controller 103. This circuit-controlled speak of as the circuit-controller of one of the clutchcircuits for the reason that when it is pulled forward it makes or closes that clutch-circuit-to wit, the following-described clutchcircuit: from negative side of the source of electricity, switch 88, wire 8'7, wire 104, stud 105, bridge 106 on circuit-controller 103, stud 107, wire 108, electric clutch mechanism 16 16 to the right, as seen in Fig. 2, which electric clutch mechanism I have designated in Fig. 2 by the letter A to distinguish it from the electric clutch mechanism 16 16 to the left in Fig. 2, which I have designated by the Some of these circuits are.

102, switch 88, to the positive side of the source of electrical energy. Thus by closing circuitcontroller 103 through the energizing of magnet 100 electric clutch mechanism 16' 16 (A) is energized, the two parts of the clutch are gripped together, and shaft 6 is caused to rotate with gear-wheel 12, which wheel, as explained above, is constantly rotating, being driven by the rotating mechanism of the press. Rotation is thus imparted in one direction to shaft 6. The operator then moves the handwl eel until finger 94 rests upon the next stud 82 the operatingcircuit above described is circuit-controller of the said clutch-circuit.

broken and electromagnet 100 is denergized. In order to prevent circuit-controller103 from falling back and breaking the circuit through electric clutch mechanism 16 16 (A) and stopping the rotation of shaft 6 at once, I provide a catch 113, which has a toe 114, adapted to fall behind andseize circuit-controller 103 when it is closedby magnet 100 and to hold the circuit-controller in itsclose'd position until the catch is withdrawn, as hereinafter described. By these means shaft 6 continues to rotate. As soon as finger 94 reaches stud 82 the following-described operating-circuit is closed-namely, from negative side of the battery, switch 88, main-line wire 87, wire 86, parts 85 93 92' 94, stud 82, wire 115, electromagnet 116, wire 117, main-line wire 102 to positive sides This operating-circuit when closed energizes magnet 116, and this magnet closes circuit-controller 118. As this circuitcontroller closes it closes a clutch circuit through electric clutch mechanism 65 65. I therefore call the circuit-controller 118 the This clutch-circuit through electric clutch mechanism 65 65 is as follows-viz, from negative side of the switch 88, main-line wire 87, studs and bridge upon circuit-controller 118, Wire 119, electric clutch mechanism 65 65, wire 120, studs and bridge on circuitcontroller 118, main-line wire 102 to positive side. As soon as the circuit-controller 118 is closed by magnet 116 catch 121 seizes and holds it in its closed position in the manner above described. Thus by moving finger 94 upon stud 82 the operator has closed an operating-circuit. The latter has closed the clutch-circuit through clutch mechanism 65, thus causing the two parts ot'the clutch to revolve together, taking with them gear- Wheel 66. As above described, this gear-wheel 66 communicates motion through a train of gearing and causes all of the printing-cylinders in the press to be moved inward against the. impressiondrum. The operatorv then moves the hand-wheel; but although the circuit through magnet 116 is broken as finger 94 leaves stud 82 'catch 121 holds circuit-controller 118 in its closed or operative position, thus maintaining the closed circuit through The moment finger 94 leaves stud 82 mechanism 38 38. sists of the following: from negative pole,

clutch mechanism 65 65*. Hence gear-wheel 66 continues to rotate until stopped,.as hereinafter described. a The operator then turns magnet 123 closes circuit-controller 126. This circuit-controller is the circuit-controller of the clutch-circuit through electric clutch This clutch-circuit con switch 88, main-line wire 87, Wire 127, studs and bridge on the circuit-controller 126, wire 128, electric clutch mechanism 38 38, wire 129, studs and bridge on circuit-controller 126, wire 125, main-line wire 102, switch 88 to positive side. Similarly catch 130 seizes and holds circuit-controller 126' in its closed position. In this position clutch mechanism 38 38 is energized and causes gear-wheel 42 to rotate with shaft 6 andto drive a train of gearing connecting with .the damping-frames of the press. The damping-frames are thus moved so as to bring the damping-rollers against the'printing-cylinder and into operative position for damping the latter cylinders. The operator then moves hand-wheel 89 until finger 94 rests upon the stud 82 This closes an operating-circuit which closes a clutchcircuit through electric clutch mechanism 18 18 to movethe inking-frames. The said operating-circuit consists of the following: negative pole, switch 88, main-line wire 87, wire 86, parts 85 93 9294, stud 82, wire 131, electromagnet 132, wires 133 134, main-line wire 102, switch 88 to positive side. -When this circuit is closed, magnet 132 closes circuitcontroller 135, thus closing the clutch-circuit through electric clutch mechanism 18 18*.

.This clutch-circuit consists of the following:

negative pole, switch 88, main-line wire 87,

wire 136, studs and bridge on circuit-controller 135, wire 137, electric clutch mechanism 18 18 ,'wire 138, studs and bridge on the circuit-controller135,wire 134, main-line wire 102, switch 88 to positive side. (latch 139 holds circuit-controller 135 in its closed position. Thus electric clutch mechanism 1818" is energized and causes gear-wheel 21 to rotate with the shaft and through its train of gearing to move the inking-frames throughoutthe press to bring the inking rollers against the printing-cylinders.

When the various parts of the press to be movedthe printing-cylinders, the dampingframes, and the inking-frameshave all been 'moved into their operative positions ready for printing, the operator moves the handwheel, so as to bring finger 94 upon stud 82 This closes a circuit througha magnet, which IIO sta es 1 t attracts and withdraws catch 113, permitting the circuit-controller 103 to drop backward into its open or inoperative position, thus deenergizing electric clutch mechanism 16 16 (A) and disconnecting gear-Wheel 12 from shaft 6. Therenpon shaft 6 ceases to rotate and with. it gear-wheels 66, 42, and 21 cease to rotate unless these gear-wheels have been sooner automatically stopped, as hereinafter described, thus stopping the movement of the printing-cylinders, damping-frames, andinking-frames throughout the press. This cir cuit, above referred to, I speak of as a releasing-circuit, inasmuch as it releases the circuit-controller of one of the clutch-circuits. This releasing-circuit consists of the following parts-viz., negative pole, switch 88, mainline wire 87, wire 86, parts 85 93 92 94, stud 82 wire 140, electromagnet 141, wire 142, end of wire 109, studs and bridge of circuitcontroller 103, (inasmuch as the circuit-controller is in its closed position,) wire 101, main-line wire 102, switch 88 to positive pole. As this releasing-circuit is thus closed by the operator electromagnet 141 attracts and withdraws catch 113, which is its armature-lever, withdrawing tooth 114 from contact with circuit'controller 103 and permitting the latter to fall back into its open or inoperative position, thus denergizing electric clutch mechanism 16 16 (A) and causing shaft 6 to cease to rotate, as above described. In this position the respective parts of the press-the printingcylinders, damping-frames, and inking-franc es-are in their forward or operative position, where they are prepared to do the work of damping, inking, and printing.

\Vhen the operator desires to move these various parts of the press back to their original positions-as, for example, after the printin has been completed-he turns the handwheel until finger 94 rests upon stud 82 This closes an operating-circuit which closes a circuit-controller in a clutch-circuit through clutch mechanisms 16 16, (13,) thus energizing this electric clutch mechanism and cansing shaft 6 to rotate with gear-Wheel 12. Shaft 6 is thus driven in a direction reverse to the rotation first imparted to it. The above operating-circuit consists of the following parts: negative pole, switch 88, main-line wire 87, wire 86, parts 85 93 92 94, stud 82 wire 143, electromagnet 144, wire 145, wire 146, niain-line wire 102, switch 88 to positive pole. Magnet 144 when thus energized closes circuit-controller 147, thus closing the clutchcircuit, which is as follows-namely, negative pole, switch 88, main-line wire 87, wire 148, studs and bridge of circuit-controller 147, wire 149, electric clutch mechanism 16 16 (13,) wire 150, studs and bridge of circuit-controller 147, wire 146, the main-line Wire 102. Catch 151 seizes and holds circuit-controller 147 in its'closed position until released, as hereinafter described. The operator then moves finger 94 upon stud 82 closing the 0perating-circuit through magnet 132, above detil finger 94 rests upon stud 82- scribed, thus closing circuit-controller 135 of the clutch-circuit through clutch mechanism 18 18, above described. This causes gear 21 to rotate with shaft 6, and through its train of gearing, above described, moves the inkingframes backward away from the printingcylinders or into their inoperative positions. Catch 139 seizes and holds circuit-controller 135, thus insuring a continuance of this movement until its completion and discontinuance, as hereinafter described. The operator then moves the hand-wheel, bringing finger 94 into contact with stud 82, thus closing the operating-circuit through magnet 123, the latter closing circuit-controller 126 in the clutchcircuit through electric clutch mechanism 38 38% This connects gear-wheel 42 with shaft 6, and, through its respective train of gearing, moves the press, causing them to move so as to take the damping-rollers away from the printingcylinder. Catch 130 seizes and holds circuitcontroller 126 until this movement is com pleted, as hereinafter described. The operator then moves the hand-wheel until finger 94 touches stud 82K This closes the operatingcircuit through magnet 116, closing circuitcontroller 118 to close the clutch circuit through clutch mechanism 65. This connects gear-wheel 66 with shaft 6, and, through its appropriate train of gearing, gear-wheel 66 moves all the printing-cylinders of the press away from the impression-drum, catch 121 seizing and holding circuit-controller 118 in its closed position during this movement. The operator then moves the hand-wheel un- This closes a releasing-circuit to withdraw catch 151 to permit circuit-controller 147 to open, thus breaking the clutch-circuit through clutch mechanism 16 16, (B.) This releasing-circuit consists of the following: negative pole, switch 88, line-wire 87, wire 86, parts 85 93 92 94, stud 82 wire 152, magnet 153, wire 154, end of wire 150, studs and bridge of circuitcontroller 147, (inasmuch as the circuit-com troller is closed,) wire 146, main-line Wire 102. Thus energized, magnet 153 withdraws catch 151 from circuit-controller 147, thus breaking the clutch-circuit through 16 16" (B) and disconnecting shaft 6 from gear-wheel12, whereupon shaft 6 ceases to rotate and with it gearwheels 66, 42, and 2lvcease to rotate.

In the above manner and by the above-described mechanismthe operator,by turninghis hand-wheel so that finger 94 makes successive contact with the different studs, first connects the shaft of the controlling-engine with the driving mechanism of the press, thus causing the shaft to be driven in one direction, and then successively closes the different operating-circuits, successively energizing the different electric clutch mechanisms controlling the movements of the printingcylinders, damping-frames, and inking'frames in order until the printing-cylinders, damping-rollers, and inking-rollers have been moved into their the damping-frames throughout ICC operative or printing positions, whereupon the printing proceeds. When the printing is completed, the operator moves the handwheel, bringing finger 9 1 into contact successively with studs 82 82 82 82 and 82 thus closing the different operating-circuits and through them the difierent clutch-circuits, causing the shaft of the controlling-engine to be so connected with the driving mechanism of the press as to rotate in a direction difierent from that of its first rotation and to connect that shaft with the different partsof the press to be moved with the dampingframes, inking-frames, and printing-cylinders, to cause them to be moved backward into their inoperative positions. When this movement is completed, the operator disconnects the shafts of the controlling-engine from its driving mechanism in the manner above described. The press is now at rest or at least is not printing. By these means the damping mechanism, inking mechanism, and

the printing-surfaces are always moved into or out of operative position independently of the ordinary operation of the press and in a fixed predetermined sequence, and the damping mechanism is always brought into operative connection with the printing-surface before the inking mechanism is brought into operative connection with the said printingsurface, and the damping mechanism is always kept in such operative connection with the printing-surface until after the inking mechanism is moved out of operative connection with the printing-surface. By these means the operator is compelled to move the parts in a predetermined order or sequence, and mistakes on the part of operators are guarded against and injury to the parts of the press avoided.

In order to cause the printing-cylinders, damping-frames, and inking-frames to stop when they have reached the limits. of their respective movements, either when movinginto operative position or out of'ope'rative position, I preferably provide means for auto matically shutting off the power for moving these various'partsin order to prevent breakage of the parts of the press and to insure that the various parts thus moved shall stop at a predetermined point My preferred mechanism for this purposel will now describe.

- It consists, generally speaking, of means, au-

tomatically actuated by the part of the press being moved at the limit of its movement, for releasing the catch which holds the circuitcontroller of the clutch-circuit corresponding to said part of the press, thus denergizing the electric clutch mechanismwhich connects the shaft of the controlling-engine with the connecting mechanism leading to the said part of the press which is being moved. In this manner the'power is shut off and the part of. .the press in question is automatically brought to astandstill. The means for accomplishing this purpose for each of the parts t0 be m0ved-namely, for the printing-cylinmechanism 65. shaft of the controlling-engine from gearders, the damping-frames, and the inkingframes-is the same. It consists of an electromagnet in a releasing-circuit controlling branches 158 and 159, each provided with a.

contact-point 160 and 161, respectively, wire 162, secured to one of the segments '7 3, which moves the-printing-cylinders toward or away from the impression-drum, as above described, wire 162 having two contact-points 163 and 164 adapted to make contact with the contactpoints 160 and 161, respectively, one set of contact-points beingbrought together when segments 73 are at the limit of their movement in one direction, and the'other set of contact-points being brought together when the segments are at the other limit of their movement, end of wire l20,studs and bridge of circuit-controller 118, main-line wire 102, switch 88 to positive pole. In this device contact-points 160, 161, 163, and 164 constitute a circuit-con troller automatically operated by the segments 73 at the limit of their movement. As shown in the drawings, when the segments 73 are at either limit of their movement the circuit through electromagnet 156 is closed, that magnet is energized, and catch 121 is withdrawn from circuit-controller 118,

- releasing the latter and permitting it to break the clutch-circuit through electric clutch This disconnects the wheel 66 and the connecting mechanism leading to the printing-cylinders, thus causing those cylinders to immediately stop. This operation is automatic and needs no supervision on the part of the operator, is simple in its operation and certain in its action, and effectuallyprevents breaking ofparts of the press, while at the same time stopping the printing-cylinders at a predetermined point with certainty and precision. In order to permit of the oscillatory movement of segment'73 without in any way interfering with the electrical connection, a part of wire 162 is made of a springy flexible character, as shown in Fig. 8. There is a similar releasing-circuit, electromagnet, and circuit-controller automatically operated by the damping-frames at the limit of their movement to automatically stop the movement of the dam ping-frames at a predetermined point for the purpose above described. This circuit conslsts ot the following: negative pole, switch 88, main-line wire 87, wire 127, wire 165, electromagnet 166,,wire 167, spring-arm 168, having contact-pin 169, projecting through near the end of arm 168 on both sides of the ceases .9

arm, contact-points 170 171, mounted on the insulation-disk 172, wires 173 174, uniting into wire 175, part of wire 129 and studs and bridge of circuit-controller 126, wire 125,1inewire 102 to positive pole. The end of wire 167 and spring-arm 168 are carried on oscillating arm 176, (see Fig. 10,) mounted on the same shaft 56 upon which is mounted eccentric 57, which oscillates wheel 58, which gives a reciprocating movement to damping-frames of the press. Accordingly as these damping-frames are movedone way or the other arm 176 closes the circuit through magnet 166, either between contact-points 169 and 170 at one limit of the movement of the damping-frames or at contact-points 169 171 at the limit of the movement in the other way. In either case magnet 166 is energized, catch 130 is withdrawn, and circuit-controller 126 is opened, denergizing electric clutch mechanisms 38 38, and thus disconnecting the shaft of the controlling-engine from gearwheel 42 and the connecting mechanism leading to and operating the damping-frames, causing those damping-frames to stop their movement at once. A similar circuit, electromagnet, and circuit-controller are automatically actuated by the movement of the inking-frames at the limits of their movements. This circuit and connections consist of the following: negative pole, switch 88, main-line wire 87, wire 136, wire 177, electromagnet 178, wire 179, swinging arm 180, carrying the end of wire 179, spring 181 upon arm 180 and electrically connected with wire 179, contact-point 182, projecting on both sides of spring 181, contact-points 183 184, wire 185 186, uniting into wire 187, end of wire 138, studs and bridge of circuit-controller 135, wire 134, main-line wire 102 to positive pole. Arm 180 and its connections may be placed upon any one of the different sets of inking-frames in the press. As the inking-frames move one way or the other arm 180 moves with them, making contact-points 182 183 to close the circuit through .magnet 178 when the inking-frames are at one limit of their movement,and m akin g contact-points 182 and 184 make contact and close the circuit through the magnet when the inking-frames are at the limit of their movement in the other direction, in both cases withdrawing catch 139 from circuit-controller 135 and causing the lat ter to fall back and break the circuit through electric clutch mechanism 18 18 2 This disconnects gear-wheel 21 and the connecting mechanism leading from it to and operating the inking-frames to the shaft from the eontrolling-engine,thusimmediatelystoppingthe inking-frames in their movement. While the operator by closing the circuits through releasing-magnet 141 or 153 can disconnect the shaft of the controlling-engine from the driving mechanism which is imparting motion to it, and thus can at will stop the movements of the different parts of the press, the above automatic means guards against any neglithe various gence on the part of the operator and insures the stoppage of each difierent part of the press being moved exactly at a predetermined point. It is evident, of course, that in place of the electric circuits employed in this antomatic releasing mechanism mechanical means automatically actuated by the difierent parts of the press being moved could be substituted in its place without departing from my invention. I prefer, however, the arrangement herein shown and described for this purpose. In Figs. 14, 15, 16, and 17 1 have shown a form of magnets and connections which I prefer to use, although'any other suitable form may of course be employed. The moment circuit-controller 118 or 126 or 135 closes its releasing-magnet will be instantly energized, inasmuch as contact-points 160 163 or 169 and 170 or 182 and 183 are then in contact with each other. This would prevent catch 121 or 130 or 139 from seizing and holding its corresponding circuit-controller. In order to overcome this, it is necessary for the operator to keep the contact between finger 94 and the different studs closed for a sufficient length of time to start the movement of the corresponding part of the press, and thus break the contact between the contact-points referred to. The moment this contact is broken the catch at once becomes operative.

Figs. 18, 19, 20, and 21 show a box 188, in which I place the different circuit-controllers and their catches, electromagnets, and connections. The bottom of the box 189 is made of wood or other suitable insulating material. The ends 190 190 are made, preferably, of slate. Over the wooden bottom I preferably place a layer of slate 191. The sides of the box 192 192 are made of glass, so as to show the contents of the box and the position of the different circuit-controllers. In order to make the latter more. clearly visible, I preferably place incandescent lamps 193 in the interior of the box to light up the same. 194 isa base or platform containing the circuitcontroller 118, catch 121, electromagnets 116 156, and their respective contact points, bridges, and wire connections. 195, 196, 197, and 198 are similar platforms containing, respectively, circuit-controllers 147, 103, 126, and 135 and their respective magnets, catches, and other connections. Figs. 18 and 19 also show various binding-posts used in the system, which may of course be of any form or arrangement desired and will therefore not be further explained' Figs. 14 to 17, inclusive, show the preferred form of platform, circuit-controller, catch, electromagnets, contact-points, and wire connections preferably employed by me. 199 represents a circuit-controller having a head 200, composed of insulating material and carrying bridges 201. The circuit-controller is normally held outward, as shown in Fig. 14, by means of spring 202. Oircuitcontroller 199 is an armature-lever carrying ar mature 203 of electromagnet 204. This is the electromagnet of the operating-circuit and controls the circuit-controller 199, which corresponds with the circuit-controller of the clutch-circuits above described. The catch of the circuitcontroller is represented in these figures by spring-controlled arm 205, which is normally held in its upward position by means of spring 206. Catch 205 passes through a slot 207 in circuit-controller199 and has a toe 208, which slips behind and holds circuit-controller 199 when pulled forward by the magnet 204. "When this is pulled forward, bridges 201 make contact with contact-points 209. The faces of bridges- 201 are preferably made wedge-shaped, and theends of contact-points 209 are made of the shape shown in Fig. 14, in order that a close contact may be made and maintained at all times between the bridges and the contact-points. Catch 205 is the armature-lever of armature 2 1 0 of electromagnet 211. Magnet 211 corresponds with the releasing-magnets 156, 153, 141,166, and178. The operation of these parts has already been suificiently described.

In the'form of controlling-engine shown in the drawings the driving mechanism of the controlling-engine consists of shaft 6 or 6 6 and its connections. The source of power for the controlling -engine is the driving mechanism of the press, acting through shaft 10 and its connections, the two said driving mechanisms forming the driving mechanism for moving the different parts of the press. The connecting mechanism between the driving mechanism of the controlling-engine and the damping-frames consists of the train of gearing comprising gear 42 and 43, shaft 44, and the other gearing connecting said shaft 44 with the damping-frames. The connecting mechanism between the driving mechanism of the controlling-engine and the inkingframes consists of the train of gearing comprising gear 21 22, shaft 23, and the other gearing connecting said shaft 23 with the ink-frames. The connecting mechanism between the driving mechanism of the controlling-engine and the printing-surfaces consists of the train of gearing comprising gearwheel 66 67, shaft 68, and the other gearing connecting said shaft with the printing-sur faces.

the presswith the driving mechanism of the controlling-engine consists of the two clutch gear-wheels 12 and 12 and electric clutches 16 16 the driving mechanism of the controllingengiue with the connecting mechanism leading to the damping-frames consists of the V gear-wheel 42 and electric clutch 38 38*.

Similarly the clutch mechanism to connect the driving mechanism of the controllingengine with the connecting mechanism leading to the inking mechanisms consists of gear-wheel 21 and electric clutch 18 18*,

The clutch mechanism to connect the source of powerthe driving mechanism of The clutch mechanism to connect.

and the mechanism to connect the said driving mechanism with the connecting mechanism leading to the printing-surfaces consists of gear-wheel 66 and electric clutch 65 In the drawings in this case my controllingengine has been shown as controlling the movements of the printing, inking, and damping devices only; but it can of course be applied to control the movements of any other part of the presswhich it may be desired to move.

The driving mechanism of my controllingengine may be driven from any suitable source of power, although I prefer to drive it, as shown in the drawings, by the driving mechanism of the press.

In the preferred form of my improved device, as shown,the connecting mechanisms intervening between the driving mechanism of the controlling-engine and the dilferent parts of the press are shown as consisting of trains of gearing. Such connccting'mechanisms may, however, consist of any other form of mechanism suitable for the purpose. Likewise the means for operating the clutch mechanisms may be varied from those shown in the drawings.

My improved devices are simple in character, compact in form, and are easily operated. By means of them the movements of difierent .parts of the press are easily and quickly controlled, and the operator is enabled to maintain at alltimes complete and ready control of such movements to move such parts to any desired position with certainty and precision and to time such movements with exactness.

This application is designated as Case A to distinguish it from two other applications for controlling-engines filed by me simultaneously herewith and designated as Case B and CaseC.
